There’s one American bird that has an unusual habitat problem. Chimney Swifts have adapted in the past as humans encroached on their territory. But now changes in human behavior are presenting new problems for the birds. And some people are trying to help them adapt again. Stephanie Hemphill reports.

In his dad’s window-and-door warehouse in the Minneapolis suburbs, Derek Meyer is supervising the boys in his scout troop as they build a wooden tower for Chimney Swifts.

They’re using rough plywood to build a narrow box twelve feet high with an opening about a foot square.

Derek is doing this project to earn the rank of Eagle Scout. In the process, he’s learned a few things about the lives of Chimney Swifts.

“They originally lived in hollow trees but when the settlers from Europe came over they started destroying the trees, so they decided to live in the chimneys, and then people started putting wire over their chimneys, so over the last 40 years they’ve lost half of their population.”

Not just wire, but rain caps and other devices to keep moisture and critters out of chimneys.

The new home these boys are building for Chimney Swifts is destined for the nature center next to a nearby school. The school district was planning to tear down an old brick chimney as part of a remodeling project. Rebecca Field found out about that, and she tried to stop it.

“I said, wait a minute, I’m sure there are Chimney Swifts in there and they’re really good birds because they eat about 2,000 insects a day, each of those birds. And their favorite insect is the mosquito.'”

Field is on the board of Audubon Minnesota, and she’d been watching the swifts hanging around the chimney in the evenings. Individually they look like fat cigars with wings, but when they get ready to swoop down into the chimney for the night, there are so many of them, they look like a funnel cloud.

“How they communicate I have no idea, how they put the brakes on when they dive into that chimney so quickly, it’s a mystery but it’s a fun thing to watch.”

In the end the school district decided to leave the chimney up.

So now, a few weeks later, and just in time for the Chimney Swifts to fly back up from the Amazon, the tower is standing on a concrete pad at the school’s nature center.

School naturalist Marleane Callaghan has already brought all her classes, grades three-through-five, to check it out.

“We’ve talked about the bird, what it looks like, the dimension of it, I’ve invited them to come back with their parents to watch in the school parking lot in the evening up at the high school where they’ve left the chimney, and then to walk on down, to be able to identify them.”

This project is part of an effort by Audubon groups all over the country to raise awareness of Chimney Swifts and their need for homes.

In Minnesota, project director Ron Windingstad wants to convince homeowners to make existing chimneys more welcoming. He says people can take the caps off their chimneys during the summer, or just raise them high enough so the birds can fly in from the sides.

Soon these school kids will be able to see the amazing acrobatics of the Chimney Swifts. Windingstad says they hardly ever stop flying, from morning til night. They’ll even sip water and take a bath in a nearby pond, without stopping.

“They’ll scoop down, lower their bill, and fly across it and drink in the water. They’ll use some of these shrubs around here to break off little twigs about the size of a wooden matchstick or toothpick actually, and use that to build their nests, and they do that while flying as well. They are marvelous creatures.”

Personal Care Products and ADHD

There’s been a rise in reports of behavioral disorders in kids over the past decade or so. Some researchers say genetics, lack of sleep, and chaotic households all contribute to things like ADHD. Now researchers say another cause could be personal care products. Julie Grant reports:

Transcript

There’s been a rise in reports of behavioral disorders in kids over the past decade or so. Some researchers say genetics, lack of sleep, and chaotic households all contribute to things like ADHD. Now researchers say another cause could be personal care products. Julie Grant reports.

Researcher Stephanie Engel at Mount Sinai College of Medicine says we’re all exposed to a group of chemicals called phthalates all the time. Heavier ones are used in plastics. Lower weight phthalates are used in fragrances, shampoos, cosmetics and nail polishes, to make them work better and last longer.

Some studies have looked at the relationships between phthalates and problems in reproduction. But Engel says phthalates are can be toxic to the nervous system. So she and her colleagues wanted to see if exposure to phthalates in the womb affected children’s brain development.

“WE ENROLLED A GROUP OF WOMEN WHO WERE PREGNANT AND RECEIVING PRENATAL CARE AT MT. SINAI. AND WHEN THEY WERE PREGNANT, WE COLLECTED A URINE SAMPLE FROM THEM. AND WE CONTINUED TO FOLLOW THE WOMEN AND THEIR CHILDREN FOR THE NEXT TEN YEARS.”

Engel says researchers tested the urine of the pregnant women in the study.

That’s because when we rub on lotion or use shampoo, phthalates are absorbed into our bodies, processed and eliminated.

She says the women who had higher levels of the pthalates during pregnancy reported more behavioral problems as their children got older:

“THEIR PARENTS, THEIR MOTHERS, REPORTED THEIR BEHAVIOR AS MORE DISRUPTIVE AND MORE PROBLEMATIC. SO THEY TENDED TO BE MORE AGGRESSIVE, HAVE MORE ATTENTION PROBLEMS, HAVE MORE CONDUCT PROBLEMS AND ALSO EXHIBIT MORE SYMPTOMS OF DEPRESSION.”

Engel says the problems looked like the types of problems found in children with ADHD: attention deficit hyperactivity disorder.

She says no behavior effects were found for the phthalates used in vinyl toys and other soft plastics. But the higher the mother’s exposure to phthalates found in personal care products, the more the symptoms were manifested by their children. The study was published in the peer-reviewed journal – Environmental Health Perspectives.

“I CANNOT SEE HOW THE CONCLUSIONS THAT ARE REACHED ARE SUPPORTED BY THE WAY THE STUDY IS DONE.”

John Bailey is chief scientist for the Personal Care Products Council. That’s the trade association for the companies that make things like cosmetics, shampoo and nail polish.

He says in any study that correlates a behavior to an outcome – there needs to be a control for outside influences.

“IN THIS CASE THOSE CONTROLS, AND AGAIN THESE ARE EXTREMELY IMPORTANT, NO MATTER WHAT TYPE OF STUDY YOU’RE DOING, ARE NOT THERE. THEY’RE NOT CONTROLLING FOR THE GENETICS OF THE CHILDREN, THEIR HOME ENVIRONMENT, THEIR DIETS.”

Without those kinds of controls, Bailey says there’s no way to draw a conclusion from the study.

Other scientists who’ve looked at phthalates say the Mount Sinai study shows a new area of concern about these chemicals. But it needs to be replicated by other research.

Still, this isn’t the first time this type of correlation has been made. In a study published last year, Korean researchers linked childhood exposure to phthalates to ADHD.

Researcher Stephanie Engel says environmental toxicants, like phthalates, clearly play a role in child neurodevelopment.

“THERE’S NOTHING ELSE THAT COULD EXPLAIN THE RESULTS THAT WE’VE OBSERVED. WE SPENT OVER A YEAR PROCESSING THIS DATA AND LOOKING AT IT IN MANY DIFFERENT WAYS. IT IS WHAT IT IS. THESE ARE THE RELATIONSHIPS.”

Engel says more study needs to be done. In the meantime, she says pregnant women might want to avoid phthalates in personal care products. They’re not listed on the label – but she says anything that has “fragrance” on the ingredients list probably contains phthalates.

Being Green and Being Bad

  • Researchers find, for example, being a green shopper might lead to some not so green behavior. (Photo courtesy of USDA)

We might think it’s virtuous to
buy things that are environmentally-
friendly: recycled paper saves trees,

good, we sometimes use that to excuse
being bad. Julie Grant reports:

We might think it’s virtuous to buy things that are environmentally-friendly: recycled paper saves trees, natural cleaners cause less pollution. But new research finds that when we’re good, we sometimes use that to excuse being bad. Julie Grant reports.

Nina Mazar wants more people to buy green products. She’s a marketing professor at the University of Toronto business school. And she thinks people should spend money on things that aren’t harmful to the environment.

But Mazar had some concerns. Research in other areas shows that if people do one thing they define as moral or virtuous – say, helping others or being politically-correct – they are more likely to transgress in other areas.

Mazar wanted to see if the same was true for buying green products.

“In our society, it seems at least, that green consumption is being moralized. And we thought, well, if it’s being moralized, maybe it can have some negative effects.”

That’s the key: if we moralize one behavior, Mazar says, we’re more likely later to do something negative.

So, first they did a survey, and found that, yes, people believe that consumers who buy environmentally-friendly and organic products are more likely to be ethical, cooperative and altruistic.

Then they tested it. They gave money to two groups of college students – one group was asked to buy products in a regular grocery store, the other in a store with mostly green products.

Afterwards, Mazar and her team set up a computer game. The students could see how much money they were making as they played – and they could easily cheat . When the game was over, they were told to take the amount they’d won out of an envelope.

“And what we found was that people who purchased in the green store, as opposed to the conventional store, cheated more on that particular subsequent task, and they actually took out more money out of the envelope than they were supposed to. So not only did they cheat, they also stole money from us.”

If students were totally accurate, they could have won $2.07. Those who had purchased green products went home with $2.90 in their pockets.

Mazar says this finding about green consumption fits right in with the theory called moral regulation or licensing.

“Whenever we engage in virtuous behavior, whenever we had done a good deed, we get a boost in our moral self worth, which will license us further down the road to transgress.”

This has been studied for years in the opposite direction. People who do something bad subsequently do good things to cleanse themselves.

But researcher Sonya Sachdeva says lots of new evidence is coming in that moral cleansing works both ways. She’s a PhD student at Northwestern University. And says she noticed this in herself when she started taking the bus to school.

“And at first, when I would take the bus, it took forever and I just wasn’t used to it. But the fact that I thought that I was doing this really good thing made me feel morally licensed.”

Sachdeva says each person has different things that make them feel this way.

Everyone in the green consumption study was a college student. Sachdeva says they might not be used to buying green products, so they get a boost of self worth when they do. And then might feel morally licensed to transgress: to cheat and steal.

But she says people who buy green and organic products all the time might not get that same boost of self worth and so might not have the backslide. In the same way her attitude toward riding the bus has changed.

“But over time, now that I’ve been taking the bus regularly for the past couple of years, I no longer get that same kind of warm glow feeling, because I’m used to it and my reference point has changed.”

The researchers say there is something practical we can learn from this. If we want people to be more environmentally friendly, the message should not be that be that this will make us better, more virtuous people. But it’s simply what we should do.

Saving the Orcas

For many people orca whales are very
familiar. Think Shamu. We’ve even given the wild
killer whales of the Pacific Northwest individual
names. But there’s still a lot we don’t know, like
where the whales go and what they eat. Now that they’re
listed as endangered, those have become important
questions. Liam Moriarty accompanied a research
crew trying to get answers:

Killer whales are sloppy eaters, so one way to study their diet is to
scoop up the leftover crumbs. Robin Baird says another way is to
study what comes out the other end.

“And so we basically follow behind the whales and pick up whatever
they leave behind, so either bits of fish if they’re actually catching
prey, or fecal material which we can use to look at what they’re
feeding on using genetic analysis.”

Baird is a biologist with Cascadia Research in Olympia, Washington.

(outboard motorboat sounds up)

On this morning, Baird, biologist Brad Hanson, and several other
researchers are piled into a 19-foot inflatable boat. We’re heading out
from Friday Harbor, north of Seattle to look for whales. We head
toward the Canadian border, keeping our eyes peeled. A while later,
we locate a group of more than a dozen whales.

(boat slows down)

Now comes the tricky part. The game plan is to pick an animal to
follow, and hope it leaves a specimen in its wake.

Baird: “We’ll come along side this one, get an ID then we’ll start a
flukeprint on her.”

Whales are surfacing and diving all around us.

(whale exhalation)

Researchers call out sightings, directions and distances …

“Multiple targets. Two animals. (How far?) 100 meters.”

Robin Baird maneuvers the boat into the wake of a passing whale.

“Oh, fish in mouth! Eleven’s got … the male’s got a fish in mouth!”

Researcher Greg Shorr stands in a pulpit at the bow of the boat with
a long handled pool net, looking intently into the water for the telltale
glitter of fish scales.

“OK, dip!”

He dips the net and comes up with a few scales and bits of tissue.

(whale breath)

Soon we’re tracking other orcas.

Hanson: “Chase! Underwater chase, 12 o’clock! Another target up,
125 behind us at 5 o’clock … might be chasing something … Yep!
Definitely chasing something! Two animals back there, three
animals!”

We spend over an hour tailing whales and dipping pool nets that
mostly come up empty.
(whale breath)

Getting this up-close and personal with the whales would get anyone
who doesn’t have a federal research permit ticketed for whale
harassment … But this kind of work is one important way to get
information that could help save the orcas from extinction.
Eventually, the whales move on. We make the long trip back.

(boat motors up, fades)

(brewpub noise)

That evening, in a dockside brewpub, Brad Hanson and Robin Baird
reflect on the day’s work; twelve hours on often-choppy seas. Baird
says that’s what it takes to get close to the whales.

“If we want to be able to really understand what they’re doing, we
have to be able to see the fine details of their behavior. And the only
way we’re going to se those fine details is if we’re actually close
enough to see whether a whale has a fish in its mouth when it comes
up to the surface.”

Hanson says that approach is paying off.

“Some 30 years we’ve known all these individual animals and people
have spent a lot of time looking at them, but we are seeing things in
the last couple of years that other people have not seen.”

For instance, orcas sometimes play with their food or share prey with
each other. Analysis of fecal samples has pinpointed what kinds of
fish the whales eat, and when. Observations like these have given
researchers a better picture of how the animals interact with their
habitat. And that fills in a few more pieces of the puzzle they hope will
lead to recovery for the Pacific Northwest’s endangered killer
whales.

Wildlife experts hope an experimental flock of whooping cranes
will lay more eggs this spring. The first egg produced during the
experiment was recently found damaged. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:


Scientists working on the project to develop 25 nesting pairs of
migrating whooping cranes in the eastern U.S. hope this is the year the
young cranes start to produce offspring.


But Michael Putnam of the
International Crane Foundation says one obstacle to the hatching of
crane eggs may be inexperienced parents.


“Once they do produce a fertile egg, then the birds have to exhibit the
right behaviors to tend the nest, incubate… and we’ve found some of
our birds- The females might be very good incubators at the
beginning, but it may take the male a year or two to catch on that’s
supposed to take a turn sittin’ on the egg.”


Putnam says other difficulties may include predators eating the eggs.
if the birds are successful, it’ll be the first whooping crane egg to
hatch in this part of North America in more than a century.

How Long Do You Keep a Polluting Heap?

Industries and companies get labeled as “polluters.” But what do you do when you find out you’re a pretty big polluter yourself… and you find out it’s going to cost you a lot of money to fix the problem? As part of the series, “Your Choice; Your Planet,” the Great Lakes Radio Consortium’s Rebecca Williams finds herself in that dilemma:


(sound of car starting)


This is my ‘89 Toyota Camry. It has 188,000 miles on it. Pieces of
plastic trim fly off on the highway, and I have to climb in from the
backseat when my door gets frozen in the winter. But I got it for free, I get good gas mileage, and my insurance is cheap. But now, it’s leaking oil – lots of oil. I knew it was bad when I started
pouring in a quart of oil every other week.


I thought I’d better take it in to the shop.


(sound of car shop)


My mechanic, Walt Hayes, didn’t exactly have good news for me.


“You know, you’re probably leaking about 80% of that, just from experience, I’d say
you’re burning 20% and leaking 80%.”


Walt says the rear main seal is leaking, and the oil’s just dripping
straight to the ground. Walt tells me the seal costs 25 dollars, but he’d
have to take the transmission out to get to the seal. That means I’d be
paying him 650 dollars.


650 bucks to fix an oil leak, when no one would steal my car’s radio. There’s no way. Obviously, it’s cheaper to spend two dollars on each quart of oil, than to fix the seal.


“Right – what else is going to break, you know? You might fix the rear main
seal, and your transmission might go out next week or something. Your car,
because of its age, is on the edge all the time. So to invest in a 25 dollar seal, spending a lot of money for labor, almost doesn’t make sense on an
older car.”


That’s my mechanic telling me not to fix my car. In fact, he says he’s seen
plenty of people driving even older Toyotas, and he says my engine will
probably hold out a while longer. But now I can’t stop thinking about the
quarts of oil I’m slowly dripping all over town.


I need someone to tell me: is my one leaky car really all that bad? Ralph
Reznick works with the Michigan Department of Environmental Quality. He
spends his time trying to get polluters to change their behavior.


“That’s a lot for an old car. If you were the only car in the parking lot,
that wouldn’t be very much. But the fact is, there’s a lot of cars just
like yours that are doing the same thing.”


Reznick says the oil and antifreeze and other things that leak from and fall
off cars like mine add up.


“The accumulative impact of your car and other cars, by hitting the
pavement, and washing off the pavement into the waterways, is a very large
impact. It’s one of the largest sources of pollution we’re dealing with
today.”


Reznick says even just a quart of oil can pollute thousands of gallons of
water. And he says toxins in oil can build up in sediment at the bottom of
rivers and lakes. That can be bad news for aquatic animals and plants.
There’s no question – he wants me to fix the leak.


But I am NOT pouring 650 bucks into this car when the only thing it has going
for it is that it’s saving me money. So I can either keep driving it, and
feel pretty guilty, or I can scrap it and get a new car.


But it does take a lot of steel and plastic and aluminum to make a new car.
Maybe I’m doing something right for the environment by driving a car that’s
already got that stuff invested in it.


I went to the Center for Sustainable Systems at the University of Michigan
and talked to Greg Keoleian. He’s done studies on how many years it makes
sense to keep a car. He says if you look at personal costs, and the energy
that goes into a making a midsize car, it makes sense to hang onto it for a
long time… like 16 years.


No problem there – I finally did something right!


Well, sort of.


“In your case, from an emissions point of view, you should definitely
replace your vehicle. It turns out that a small fraction of vehicles are
really contributing to a lot of the local air pollution. Older vehicles
tend to be more polluting, and you would definitely benefit the environment
by retiring your vehicle.”


Keoleian says if I get a newer car, it won’t be leaking oil, and it won’t
putting out nearly as much nitrogen oxide and other chemicals that lead to
smog. Oh yeah, he also says I really need to start looking today.


And so doing the right thing for the environment is going to cost me money.
There’s no way around that. The more I think about my rusty old car, the
more I notice all the OTHER old heaps on the road. Maybe all of you are a
bit like me, hoping to make it through just one more winter without car
payments.

Cities Take Aim at Roosting Crows

  • Crows are roosting in huge groups in cities all over the country. The USDA is trying to find ways to get them to go back to their natural habitat. (Photo by Paige Foster)

Flocks of crows are nothing new in most cities. In the fall and winter months, crows forage for food during the day and roost in city trees at night.

Flocks of crows are nothing new in most cities. In the fall and winter months, crows forage for food during the day and roost in city trees at night. The birds like cities because they’re safe and comfortable. The residents generally don’t like the crows, though. The Great Lakes Radio Consortium’s Skye Rohde reports:


(sound of crows)


There are a lot of crows here. About 63,000 of them are in the city. The trees are thick with them. At dawn and dusk, so is the sky. Bird feces coats city sidewalks and parked cars. Amy Emedon lives in town. She’s used to the crows.


“They make a lot of noise at night, or in the morning they kind of wake you up. But other than that, they don’t really bother me that much. They’re kind of gross, because their poop’s all over the place and they’re so loud and there’s so many of them. Like sometimes you can’t even see, like, the sky. It reminds me of that movie ‘The Birds.'”


Crows have been wintering in Auburn, New York for more than 100 years. Written records from as early as 1911 describe a very large roost downtown. Auburn has the largest crow roost in the state. This winter, city officials hired the U.S. Department of Agriculture to haze the crows.


(sound of distress calls and pyrotechnics)


Hazing means the eight USDA scientists drive around town using recorded crow distress calls, pyrotechnics and laser pointers – anything that will upset the birds and drive them out. Sometimes this includes shooting the birds, but not in New York state. Richard Chipman is the New York state director of the USDA’s wildlife services project. He says the idea is to move the birds to a more “natural” habitat.


“The goal is not to just relocate these birds and cause somebody else problems. The goal is to try to relocate them to a low-impact area to improve the quality of life of folks here in the city.”


The only problem with this plan is that the crows really like being in cities. The birds are smart. They’re communal. They recognize that they’re safer downtown than out-of-town. Kevin Mcgowan is an ornithologist at Cornell University who has studied crows for 16 years. He’s heard of large crow roosts in cities across the nation, ranging from 100 birds to two million. Mcgowan says it’s usually warmer in cities. Crows like that. And they like the big trees and streetlights.


“I think the lights is a big deal. Crows are scared of things that go bump in the night because those things eat them. And that’s pretty much great horned owls, okay? Great horned owl is probably the single scariest thing to a crow, because they come in at night when crows can’t see and owls can. And owls eat a lot of crows.”


Mcgowan says crows started settling in U.S. cities in much larger numbers in the 1970s and 1980s, after a change to the Federal Migratory Bird Treaty Act.


“In – I believe it was 1972 – there was an amendment to the act that afforded crows protection for the first time. What that meant was now you couldn’t just shoot crows anytime you wanted to. You had to do it under the direction of a state hunting season, which had regulations.”


As a result, people changed their behavior. They didn’t shoot crows as much, so the crows became less scared of them and moved closer. In other words, crows have realized that cities are safer habitats than their “natural” environment. Mcgowan says he’s seen it before.


“You have a big predator that scares away the smaller predator that’s the one that really bothers you, then it behooves you to hang around the big predator. Happens all the time around people. There are lots of things that come in to be around people because they’re relatively safe there.”


Whether the USDA can break that pattern in cities like Auburn remains to be seen. Scientists have surveyed this city and harrassed the remaining crows. But they might have to return next winter to do the same thing again. And Auburn officials, like those in other crow-filled cities, might need to consider changing those things that attract crows in the first place, rather than just focusing on scaring the birds away.

A little exposure to natural outdoor areas might go a long way toward
easing the symptoms of attention deficit hyperactive disorder in kids.
The Great Lakes Radio Consortium’s Tom Rogers has more:


Previous studies linking the outdoors to relaxation prompted University
of Illinois researchers to survey the parents of more than 400 children
diagnosed with ADHD. The researchers asked parents to monitor
their kids’ behavior and performance after play or study periods
indoors, outdoors in an urban setting like a parking lot, and outdoors
in greener areas.


Francis Kuo co-authored the study. She says the natural settings
seemed to improve symptoms.


“This doesn’t have to be something spectacularly natural. Just getting
your kid out in a green, tree-lined street would be good, or in the
backyard, or even the neighborhood park. You don’t have to take them
to Yosemite for these benefits.”


The study didn’t make any conclusions about whether nature could take
the place of medication, but Kuo says there’s a real potential that it
could at least help kids who don’t tolerate drug treatment well. The
study appears in The American Journal of Public Health.

Why We Waste

A new study from the University of Illinois finds that a surprising
number of the things we buy at the grocery store never get used. Brian
Wansink is a Professor of Marketing at the U-of-I. The Great Lakes
Radio Consortium’s Lester Graham talked to him about why people spend
money on products they never get around to opening:

Transcript

In the back of your cabinets you’ll likely find canned goods or other products you bought years

ago, but never opened. Brian Wansink found as much as twelve percent of the products they buy are

never used.


“In almost all these cases – er – in about three-quarters of the cases, the abandoned products, or

these castaway products that people have in their cupboards, end up being bought for

over-ambitious reasons. They’re essentially events that never happen or for recipes that we never

got around to making or things like that.”


Wansink says when they were asked how they planned to dispose of their abandoned products, more

than fifty percent of the homemakers surveyed said they would end up throwing the items away

rather than keeping them or donating them to a food pantry.


For the Great Lakes Radio Consortium, this is Lester Graham.

Inner-City Children and Lead Exposure

Many inner-city homes built before World War Two still contain lead paint-making them harmful environments for children. An estimated twenty-percent of inner-city children have dangerous levels of lead that could be hampering their central nervous systems. Researchers are trying to find out what long-term effects lead exposure in the home has on children. And they’re testing a drug that might reverse those effects.
